+# BUILD_PR_LEVEL_19_12_REVALIDATE_AND_PROMOTE
+
+## Purpose
+Re-run full validation after Level 18 completion and prior fixes; promote remaining Level 19 tracks to [x] only if clean.
+
+## Scope
+- Validation only
+- Status update only on success
+- No feature work
+
+## Steps
+1. npm test
+2. node ./scripts/run-node-tests.mjs
+3. npm run test:launch-smoke
+
+## Acceptance
+- If ALL PASS → set all remaining Level 19 items to [x]
+- If ANY FAIL → do not promote; record failures
